Ten months after shipping a preview version of MindExpander, MindVision Software has released MindExpander 1.0, a free competitor to Aladdin Systems’ ubiquitous StuffIt Expander. Like StuffIt Expander, MindExpander can expand the following formats: StuffIt 4.5, Zip, gzip, MacBinary, and BinHex. Although it doesn’t support the common StuffIt 5.0 or uuencode formats (for those, it calls other helper applications, such as StuffIt Expander 5.1), MindExpander can convert DOS line breaks in text files to Macintosh line breaks. Other useful features in the petite and self-contained application include a slick automatic update capability, support for System 6.0 through Mac OS 9 and any Mac since the Mac Plus, and a contextual menu plug-in that’s installed by the MindExpander application itself. MindExpander is a 234K download and, as with the free Aladdin Expander for Windows, a Windows version of MindExpander is available.
